Marshall 9200 5881 100/100 Dual Monobloc Tube Set
The Marshall 9200 5881 100/100 Dual Monobloc Tube Set consists of 4 x 12AX7 and 8 x 5881 (two matched quads).
The Marshall 9200 is actually rather fetching, with a gold faceplate, Plexiglas tube window, fancy knurled gold knobs, and a prominent Marshall logo on the front. Many older players are probably familiar with the 9000 series, as they were ubiquitous in the eighties and were usually paired up with a Marshall JMP-1 preamp.
The guitarists of Iron Maiden were among the many illustrious users of these amps. The 9200 is a dual-mono amplifier, rather than a standard stereo amp. This means that its pair of 100-watt amps could be used independently.
Each side has independent Power, Standby, and Voicing switches, as well as independent controls for Gain and Presence. Powered by eight 5881, the 9200 is capable of tremendous volume, headroom, and smooth British gain. Even today, it makes a great platform for the effects aficionado.
A proper Marshall preamp makes a great match for this power amp. As this amp is somewhat less coloured than a JCM800 or other Marshall head, it will work well with just about any distortion generator you might want to use.
